MAX17043 LiPo/Li-Ion Battery Fuel Gauge Products

Description

The MAX17043 ICIntegrated Circuit by Maxim Integrated measures the voltage on a single cell LiPoLithium Polymer/Li-ionLithium-ion battery and accounts for the non-linear voltage behavior of the battery to get a charge percentage (0% empty to 100% full charge). This IC outputs the battery's voltage and percentage data over I2CInter-Integrated Circuit. Also referred to as IIC or I²C. and also has a separate alert output that tells you when the charge has dropped below a certain percentage.

Both SparkFun and DFRobot have breakout boards for this IC with external circuitry and a 2-Pin JSTJapan Solderless Terminal battery connector. The SparkFun module has pin through holes for its connections, whereas the DFRobot also has a 4-Pin GravityGravity connectors are DFRobot's name for 3 or 4 pin JST PH connectors with 2.0mm pitch. These connectors were implemented on DFRobot's boards to make it easy to plug-n-play various sensors and devices without soldering and wiring. The DFRobot Gravity connectors are cross-compatible with Seed Studio Grove and Adafruit’s STEMMA connectors. connector and an extra 2-Pin screw terminal for the battery connection.
